[SSSD-users] auto_private_groups -- How does it work?
There was a discussion on another list involving how to use sssd for
authentication on an HPC cluster, and the issue of auto_private_groups
came up.
I realized I have no idea how this works. I know sssd keeps the GID
(obviously known immediately from the UID) on the local host, but what
is stored as the primary group for such files on the fileserver? Let's
say my UID is 1562224688. How does the file server distinguish between
files that are supposed to have the GID 1562224688 vs the ones set to,
say, 1007000513 ?
Also, does this mean that sssd short circuits group authorization requests?
